Thermal Imaging Survey
An infrared thermal imaging survey reveals what the eye cannot see, hidden damp and moisture, water leaks, cold spots and heat loss, without drilling or damage. We use it to find the real cause of a problem before any treatment is recommended.

What is a Thermal Imaging Survey?
A thermal imaging survey, also called infrared thermography, uses a specialist camera to read the surface temperature of walls, floors and ceilings. Problems hidden inside the fabric of a building change how those surfaces hold and lose heat, so they show up as clear warm or cool patterns on the thermal image.
That makes it possible to see issues behind the plaster without drilling, lifting floors or opening up walls. For a damp specialist it is a diagnostic tool, not a gadget, a way to locate a leak, map the spread of moisture, or tell the difference between rising damp, penetrating damp and condensation before deciding what, if anything, needs treating.
Used properly, a thermal image is read alongside a moisture meter and a surveyor's judgement, so the picture on screen is confirmed with a hard reading rather than taken at face value.
What a Thermal Imaging Survey Detects
One survey can uncover a wide range of hidden problems, all without disturbing your property.
Hidden Damp & Moisture
Damp areas hold and release heat differently to dry ones, so trapped moisture and the true extent of a damp patch show up clearly on the thermal image.
Damp surveys →Water Leaks & Burst Pipes
Concealed plumbing leaks and tracking water can be located quickly behind walls and under floors, so repairs target the source instead of guesswork.
Penetrating damp →Condensation & Cold Spots
Cold surfaces where condensation and black mould form are easy to spot, helping separate a condensation problem from structural damp.
Condensation →Missing or Wet Insulation
Gaps, slumped or damp insulation in walls and lofts appear as cold patches, a common cause of cold rooms and high heating bills.
Ventilation →Thermal Bridging & Draughts
Cold bridges and air leaks around windows, doors and junctions that drain heat from a property are mapped so they can be sealed.
Mould removal →Hidden Defects Before Buying
A useful check before a purchase or at the end of a builder's or NHBC warranty, revealing issues a standard visual inspection can miss.
Case studies →Thermal Imaging for an Honest Damp Diagnosis
Too many damp problems are misdiagnosed. A quick visual inspection can wrongly label condensation as rising damp, leading to expensive injection treatment that was never needed. Thermal imaging helps us avoid that.
By showing the pattern and spread of moisture across a wall, the camera helps us see whether damp is rising from the ground, penetrating from outside, or condensing on cold surfaces, each of which needs a completely different fix. We then confirm the diagnosis with a moisture meter and, where rising damp is suspected, salt analysis.
The result is a survey that can just as easily tell you a problem is minor, or rule a problem out, as recommend works. That honest, evidence led approach is the whole point of using the technology.
Good to know: thermal imaging shows temperature patterns that indicate moisture, not the water itself. It is at its most reliable in the hands of a damp specialist who confirms every reading, which is exactly how we use it.
When You Might Need a Survey
How the Survey Works
Initial discussion
We start by understanding your concerns and the history of the property, so the survey targets the right areas rather than scanning blindly.
On-site thermal scan
A surveyor scans the property inside and, where useful, outside with a high specification thermal camera, capturing images of any anomalies.
Confirm the readings
Anything the camera flags is checked with a calibrated moisture meter, and salt analysis where rising damp is suspected, so findings are evidence based.
Written report
You receive a clear report with the thermal images, what they show and our recommendations, in plain language you can act on.
Next steps
If treatment is needed we explain the options and give a fixed price. If it is not, we will tell you that too.
Done Properly, or Not at All
A thermal image is only as good as the conditions and the person reading it. We do not cut corners to produce a survey that looks impressive but means little.
What Our Customers Say
Genuine reviews from Advanced Damp customers.
"I had two other damp surveys on my home and they were only interested in concluding that it was rising damp so that they could charge me a lot to inject into my walls. Matt on the other hand has proper experience and techniques with thermal imaging, and he understood what the issues really were. He gave holistic advice on how to really solve the problem, and at much less cost."
"Michael was an incredible support during a very stressful period. He provided a thorough, fair, and honest assessment, and his use of modern testing and technology ensured everything was measured accurately. Thanks to him, we now have a clear and reasonable remediation plan."
"I scheduled a pre-purchase damp survey with Advanced Damp on the advice of a Level 3 building survey. The quality of the survey, performed by Lionel, was excellent and the report was very detailed with photos throughout. The customer service was also very attentive."
